AX Gaming Rebel GeForce RTX 4070 Super X3W Max

Manufacturer: AX Gaming

The AX Gaming Rebel GeForce RTX 4070 Super X3W Max is a graphics card based on NVIDIA's Ada Lovelace architecture, produced on a 5 nm process node and equipped with a triple-fan cooling solution in a 325 mm x 119 mm form factor. It includes RGB lighting and supports ray tracing, DLSS, and DirectX 12 Ultimate, along with Intel Resizable BAR for improved CPU-to-GPU memory access. 36.13 TFLOPS of floating-point performance and 7,168 shading units define its compute profile, and the card connects to the system via PCIe 4.0 with a rated TDP of 220W.

The memory subsystem comprises 12GB of GDDR6X running at an effective 21,000 MHz over a 192-bit bus, yielding a maximum bandwidth of 504.2 GB/s. The GPU boosts to 2520 MHz from a 1980 MHz base, with 224 texture mapping units contributing to a texture rate of 564.5 GTexels/s and 80 ROPs delivering a pixel rate of 201.6 GPixel/s. ECC memory support and Double Precision Floating Point capability are both present. Display output is handled by three DisplayPort and one HDMI 2.1 port, supporting up to four monitors simultaneously, with no USB-C, DVI, or mini DisplayPort connections available.

Pros
  • Ray tracing and DLSS support are both present, enabling current-generation rendering and upscaling capabilities in compatible software
  • Four display outputs — three DisplayPort and one HDMI 2.1 — allow multi-monitor setups without additional adapters or hardware
  • RGB lighting is built in, suiting builds where interior illumination is part of the intended aesthetic
  • ECC memory support provides error correction for compute workloads where data integrity is a genuine requirement
  • DPFP support extends the card's usefulness to applications that depend on double-precision numerical computation
  • Intel Resizable BAR is supported, enabling the CPU to access GPU memory more flexibly during operation
Cons
  • At 325 mm in length, the card demands a reasonably spacious case and may not fit in smaller or mid-tower builds with limited GPU clearance
  • The 192-bit memory bus limits overall bandwidth headroom, which may become a constraint in workloads that push memory throughput
  • 12GB of VRAM may prove insufficient for users running memory-intensive tasks that require both capacity and high bandwidth simultaneously
  • No USB-C output is available, which rules out direct connectivity to displays or devices that depend on that interface
  • XeSS (XMX) upscaling is not supported, so users are limited to DLSS as the only AI-driven upscaling option
  • Air-water hybrid cooling is absent, meaning thermal management under sustained heavy loads depends entirely on the air cooler
Who is this for?

This card is well-suited to users building systems around multi-monitor setups, with four display outputs and multi-display support making it straightforward to drive up to four screens from a single card. The 220W TDP keeps power demands at a manageable level, which works in favor of builds where PSU headroom is limited, and the inclusion of ray tracing, DLSS, and DirectX 12 Ultimate covers the full feature set for current-generation rendering workloads. ECC memory support and DPFP capability also make it a reasonable fit for users who occasionally run compute or precision-sensitive tasks alongside standard graphics work.

Who is this NOT for?

At 325 mm in length, this card is not a practical choice for compact or small form factor builds where GPU clearance is restricted, as fitting it will require a full-size case with adequate internal space. Users who rely on USB-C display connectivity will find no such port available, limiting direct hookup to monitors or devices that use that interface. Additionally, those running workloads that demand both high VRAM capacity and wide memory bandwidth may find the 12GB allocation over a 192-bit bus a bottleneck, particularly as memory-intensive tasks scale up in complexity.

General info:

GPU architecture Ada Lovelace
Thermal Design Power (TDP) 220W
PCI Express (PCIe) version 4
semiconductor size 5 nm
number of transistors 35800 million
Has air-water cooling ✕
width 325 mm
height 119 mm

Designed around the Ada Lovelace architecture on a 5 nm process, the GPU integrates 35,800 million transistors and interfaces with the motherboard via PCIe 4.0. The card carries a 220W TDP and relies on air cooling, as no air-water hybrid solution is included. Its physical dimensions of 325 mm in width and 119 mm in height define its footprint, which is worth noting for case compatibility planning.

Final Verdict

The AX Gaming Rebel GeForce RTX 4070 Super X3W Max delivers a coherent feature set built around Ada Lovelace architecture, with ray tracing, DLSS, and four-display output support covering the essentials for both gaming and multi-monitor productivity use cases. Its 220W TDP keeps power requirements reasonable, and the inclusion of ECC memory and DPFP support adds a degree of versatility for compute-adjacent workloads. That said, the 325 mm length demands a full-size case, and the 192-bit memory bus sets a clear ceiling on bandwidth-intensive workloads. For users whose system and use case align with those parameters, it represents a well-specified card that handles its intended workloads without unnecessary compromise.
